Abstract
A new efficient and convenient approach toward the synthesis of pyrazoles is described. Through a Lewis acid catalyzed union of 3-ethoxycyclobutanones with monosubstituted hydrazines, a variety of pyrazole derivatives were prepared readily at ambient temperature with complete regioselectivity.
